I see 3 possibilities: 1. The original meningioma 2. The stroke, (the meningioma bled and I had a hemorrhagic stroke and some stroke survivors develop epilepsy. ) 3. The surgery to remove the meningioma and stop the bleeding.

I never asked, but I came home from rehab with a prescription for anti seizure med’s, which means that my neurosurgeon thought it likely that I would need them. And I did.
